The New England coast is beautiful and varied, from the dramatic rocky shores of Maine to the sandy beaches of Cape Cod to the rocky moraine of Long Island’s north shore. The one thing New England’s coastal waters are not is warm. I remember swimming in Maine when I was in art school in Portland: I would get all hot and sweaty by running or biking to the beach and jump in and swim a brisk few hundred yards, to the astonishment of onlookers who dared not go past their knees. For most people the swimming season in Maine consists of two weeks in August.
It is no wonder that my last several mobile saunas have found homes near the coast—what a perfect way to extend the swimming season! Cold water and saunas traditionally go together. Ideally the sauna is situated so one can plunge into a lake, pond, stream, or ocean after each round. With a sauna on wheels, you can pull up to your favorite dipping spot and indulge yourself anytime of year. There is nothing like the thrill of jumping through a hole in the ice or plunging next to a waterfall in the whiteness of winter.
The mobile unit is fairly clandestine—once the stove reaches temperature, the chimney smoke is invisible; no one will suspect you are nearly naked inside, basking until you burst out and head for the water. I haven’t had the pleasure of sauna-ing next to the ocean, but one of these days, I’ll have to travel back to Higgin’s Beach in Maine, sauna in tow, and give onlookers a thrill as I defy the icy winter water with a post-sauna dip.
You ask how or why electric mobile sauna? There are a number of reasons why going mobile makes sense, especially if you rent. No permits or special permissions are needed. You just park it in your yard and use it. You can take it with you on vacations or just for a Saturday down by the lake; you can even enter it in a parade. But why electric? Electric is no longer the inefficient dark horse of the energy world that it once was. It can be generated cleanly by wind or solar and is cheaper, cleaner, and easier to use than gas or oil. Although any purist will tell you a wood-burning sauna is the real deal, in some places, wood is not so easy—firewood may be hard to come by and difficult to store, and your neighbors may be too close for comfort or offended by the occasional whiff of smoke. Since I’ve eliminated gas burners from my repertoire (for reasons I won’t go into here), an electric mobile sauna is the next best thing. All you need is a place to plug it in.
When clients ask me to create a sauna, they often push me to do things I might have never considered doing. I’ve gotten requests to make saunas in spaces I thought were too tiny, on trailers, deep in the woods next to a pond, or to convert a cheap shed or laundry room. The most recent project to leave the shop is an electric mobile sauna. The owner has a Tesla electric car, so an electric sauna just seemed to make sense. The colors were more of an emotional choice: I painted it Sea Reflections blue like the ocean, where she likes to swim all year, with a Bonfire Red door to beckon her into the warmth of its interior and Vanilla Ice Cream trim because, well, who doesn’t like ice cream, especially after a sauna?
The how is simple: an 8 KW heater with a standard RV type hook up and a fifty-foot, very-heavy extension cord that connects to a standard car charging port (or special outdoor outlet). This will also work in many campgrounds with RV hookups. In a pinch, it can also be run off an 8500-watt generator.
This sauna also has a solar-powered low-voltage lighting system, just so there can always be light and because low-voltage systems are safer and more versatile than 120-volt lighting. I’ve been using these in some mobile wood burners and freestanding units. The neat little solar panel is a conversation starter; people are suddenly aware that the unit is more than a fancy tool shed trailer. When I tell them it’s an electric sauna, the little 25-watt solar panel gets a second glance.
I envision a fully solar electric sauna next (but probably won’t consider doing unless a client pushes me). It would have to use Tesla’s 270-pound Powerwall home battery, which has an 8kw output capacity. I imagine the entire sauna roof would a have to be a solar panel, but I haven’t done the engineering on this. This would not be cheap, but if someone out there who wants to be the first…. give me a call.
The other evening I came home from work, stressed out about the coronavirus, as many of us are, and decided to light the sauna to ease my anxiety. As it was a nice day, I decided to use the time it took heat the sauna to rake up some leaves that got matted into the lawn under a November snowfall. The breeze, which was out of the south, helped push the leaves into the hedgerow, but it also apparently helped fan the fire on my mobile wood-fired unit. By the time I put my rake down and stripped for a relaxing sauna, the thermometer was pinned at 235° F! Not one to shy away from heat, I jumped on in anyhow.
Always inquisitive, I use such opportunities to add to my knowledge about the sauna. I wondered how hot different surfaces really were with the heat so high. With only a towel on, I ran to the shop and grabbed my digital temperature gun. I use this gadget to test my saunas to make sure they are hot but also safe. The ceiling and walls were close to 300° near the stove, the walls were 230-250° above the bench, the benches were 200° and the lower benches were about 175°. The rocks were 450°—perfect for a good löyly—and the stove body glowed visibly red in the afternoon light, so about 1000° (the brightness of the glow corresponds to specific temperatures). The floor was predictably the coolest surface at 125°.
According to the Center for Disease Control, viruses cannot tolerate heat above about 167° F.1 Therefore, everything in a hot sauna from the lower bench up is guaranteed to be virus-free! No fears or worries as I bask in the heat.
That being said, despite what we all wish, the sauna will not kill a virus that has already infected you, nor will it likely destroy a virus ejected in a sneeze. The sauna will not cure you or protect you if your sauna mates are sick; in these desperate times, it’s probably best to avoid group saunas with strangers. But, taking a regular sauna will lower your stress level, boost your immunity2, and help you sleep better—all in a virus-free sanctuary.
